Actor boundary warning for @TaskLocal values

Using Swift
#1

I am getting this warning with Xcode14 beta 4 (14A5284g) as well as the 5.7 snapshot from August 2nd:

actor Test {

	@TaskLocal static var local: Int?

	func run() async {
		await Self.$local.withValue(42) {  ⚠️
			await work()
		}
	}

	func work() async {
		print("Hello \(Self.local ?? 0)")
	}
}

await Test().run()

:warning: non-sendable type '() async throws -> ()' exiting actor-isolated context in call to non-isolated instance method 'withValue(_:operation:file:line:)' cannot cross actor boundary

I am not sure how to deal with this. Is this legal code and the diagnostic is wrong or am I mis-using task local values?
